Taishin International Bank (TSIB)

Senior-programmer / RDSS

— [Batch Refactoring & UX Optimization] Addressed a critical limitation in a 2–3 hr monthly risk-management batch blocked by the .NET page lifecycle. Decoupled the process into async DB writes + AJAX polling, delivering a real-time progress bar and interrupt alert system.
— [System Integration & Data Migration] Supported the Taishin–ShinKong merger: coordinated and verified schemas for 10M+ rows of incoming data from ShinKong Financial, integrated the data sources, and modified existing batch execution applications accordingly.
— [Technical Leadership & Mentorship] Mentored onboarding engineers through dev-environment setup and system walkthroughs; coordinated task distribution to align with project timelines.
— [Automated Data Validation] Built a Python (Pandas) pre-import validation utility that identifies layout anomalies in source files, eliminating migration interruptions caused by malformed data.
— [Efficiency Gains] Guided team members on integrating AI assistant tools into daily workflows, increasing team-wide code writing and debugging throughput.
